Reaction Steps

To a mixed solution of the compound (0.30 g) obtained in Step 1, potassium thiocyanate (0.77 g) and N,N-dimethylformamide (6.0 ml) was added pyridine (0.29 ml) at 90° C. After allowing to cool to 40° C., a mixed solution of bromine (0.15 ml) and N,N-dimethylformamide (1.0 ml) was added, and the mixture was stirred at room temperature for 1 hr. Under ice-cooling, water (12 ml) was added to the reaction solution, and the precipitated solid was collected by filtration, washed with water and dried to give the title compound (0.40 g).
